FIREPROOF CEILING AND FLO-OR.

SPECIFICATION forming part of Letters Patent No. 707,201,11ated-August 19, 1902. Application filed August 2| 1901. Serial No. 70,613. (No model.)

To all whom, itmay concern.-

Be it known that I, SEBASTIAN G. BRINK? MAN, a citizen of the United States, and a resident of New York city, county and State of New York, have invented certain new and useful Improvementsin Fireproof Ceilings and Floors, of which the following is a specification.-

This invention relates to an improved fireproof floor and ceiling which is of simpl construction and combines ligli mess with superior strength.

In the accompanying drawings, Figure 1 is a vertical longitudinal section of my improved fireproof floor and ceiling on line 1 1, Fig; 6.,

Fig. 2 is a detail longitudinal section of part of the same; Fig. 3, a detail cross-section on line 3 3, Fig. 6; Fig. 4:, a'perspective view of one of the fireproof blocks; Fig. 5, a perspective view of one of the angle-plates; and Fig. 6, a longitudinal section, partly in plan, on line 6 6, Fig. 1.

a a represent the fireproof blocks, made of suitable configuration and provided with a perforation a, extending from face to face. The blocks ashould be made hollow, and the perforation a is formed within a cylindrical or hub-like section a ,which is arranged between the top plate and bottom plate of the block and is connected thereto by means of diagonal sides or braces a Fig. 4. These braces extend in the same direction as the perforated hub and at right angles to the supporting.

walls or beams of the building.

In constructing a floor and ceiling from the blocks'a the latter are, by means of suitable scafiolding, arranged in rows or tiers, and through the perforations a of each row is passed a longitudinal rod 1), which thus connects all the blocks of one and the same'row. The sides of the blocks a are preferably inclined' toward the center, Fig. 1, so that the blocks of each row form a fiat arch. The end blocks are supported directly uponthe wall A of the building and are flanked by elbowplates 0, which are strung upon the ends of rods 1). The upright section of each plate 0 is of a configuration to correspond to that of the blocks ct and is perforated at c in alinement with the perforations a. The horizontal section of each plate crests directly upon the wall A. The ends of'the rods 12 are threaded to constitutebolts, and after the parts have been assembled in the manner described nuts I), tightened upon the threads, will force the plates 0 against the end blocks a and will securely connect the component parts of each row into one firm and rigid structure. The longitudinal rods b are at suitable intervals connected to one another by transverse braces that unite the several rows into one integral structure. These a transverse braces are composed, preferably,

of three parts-viz., short transverserods (I, having threaded ends, tubular threaded coupling-sleeves d, adapted to engage said ends, and claws or hooks e. The entire transverse braces are arranged between some of the adjoining blocks a, such adjoining blocks being grooved along their sides, as at a so as to jointly form continuous perforations at right angles to the perforations a. The hooks e all face toward the center row of blocks, (marked M in Fig. 3,) so that the strain is equalized. A rod 01 is slipped through block M and adjoining blocks M,

Fig. 3, and a hook e is fitted upon each end of the rod, so as to engage rods b of blocks M. The couplings d are then screwed up against the hooks until the latter are brought into firm engagement with the rods b. After the next rows of blocks M have been laid rods 01 are passed through the openings a of the same and screwed with their inner ends into the outer ends of the couplings d, while hooks e are fitted upon the outer ends of the rods, so as to grasp the rods 6 of the rows M. In this way the construction is continueduntil the floor is completed.

It will be seen that by my improved construction of ceiling and floor I dispense entirely with the use of the usual T and I beams. The structure is of great strength, of superior lightness, and may be put up at reduced cost.

What I claim is 1. A fireproof ceiling and floor composed of perforated blocks arranged in rows, longitudinal rods engaging the perforated blocks, means fol-locking the rods to the blocks, and transverse braces at right angles to the rods, substantially as specified.

2. A fireproof ceiling and floor composed perforated blocks arranged in rows, longitudinal rods engaging the perforated blocks, hooks engaging the longitudinal rods, and. transverse rods between the hooks, substan- 5 tially as specified.

3. A fireproof ceiling and floor composed of perforated blocks arranged in rows, longitudinal rods engaging the perforated blocks, hooks engaging the rods, transverse rods engaging the hooks and blocks, and couplings for forcing the hooks against the longitudinal rods, substantially as specified.

4. A'fireproof ceiling and floor composed of blocks provided wi th perforations and grooves arranged at right angles to each other, longitudinal rods engaging the perforations, and
